This Saturday, up to 160 cyclists are scheduled to embark on a 213-mile marathon to advocate for nuclear disarmament.

The ride starts at dawn in Vaihingen-Enz near Stuttgart and passes through Heidelberg, Mannheim, Kaiserslautern and Landstuhl before returning to the starting point.

Participants are scheduled to arrive in Kaiserslautern around 1 p.m. Escorted by police, the cyclists will then continue to the Ramstein Air Base memorial around 2:15 p.m. to honor civilians who lost their lives in past conflicts, organizers said.

The riders then cycle on back toward Stuttgart, concluding around 9 p.m. back in Vaihingen.

The ride supports the United Nations nuclear weapons ban treaty, which has been ratified by 70 countries and signed by 93.

The U.S., along with other nuclear-armed nations like the UK, Russia, China and France, has opposed the treaty, arguing that it does not consider the current international security environment, according to the Nuclear Threat Initiative.
